Dynamic Configuration of IP for a Terminal Equipment Attached to a Wireless Device

1. A method of providing Internet Protocol (IP) connectivity for a terminal equipment coupled to a wireless device that is in communication with a wireless network, comprising: determining a host IP address, a router IP address, and a subnet mask; and providing the host IP address, the router IP address, and the subnet mask to the terminal equipment, wherein the host IP address, router IP address, and subnet mask are used by the terminal equipment to exchange IP packets.

2. The method of claim 1 , further comprising: receiving an IP packet from the terminal equipment; and forwarding the IP packet to the wireless network.

3. The method of claim 1 , further comprising: receiving from the wireless network an IP packet with the host IP address as a destination IP address; and forwarding the IP packet to the terminal equipment.

4. The method of claim 1 , further comprising: obtaining IP configuration from the wireless network, and wherein the host IP address, the router IP address, and the subnet mask are determined using the IP configuration obtained from the wireless network.

5. The method of claim 4 , wherein the IP configuration obtained from the wireless network includes an IP address dynamically assigned to the wireless device by the wireless network, and wherein the host IP address is set to the dynamically assigned IP address.

6. The method of claim 1 , wherein the host IP address is an IP address statically assigned to the wireless device.

7. The method of claim 4 , wherein the IP configuration obtained from the wireless network includes the subnet mask.

8. The method of claim 4 , wherein the IP configuration obtained from the wireless network includes the router IP address.

9. The method of claim 1 , wherein the host IP address, the router IP address, and the subnet mask are provided to the terminal equipment via a Dynamic Host Configuration Protocol (DHCP).

10. The method of claim 9 , further comprising: providing a server IP address to the terminal equipment, the server IP address being an IP address for a DHCP server implemented by the wireless device.

11. The method of claim 10 , wherein the server IP address is set to the router IP address.

12. The method of claim 10 , further comprising: receiving an IP packet from the terminal equipment; determining whether the IP packet is intended for the DHCP server; and processing the IP packet at the wireless device if the IP packet is intended for the DHCP server.

13. The method of claim 12 , further comprising: sending a DHCP response back to the terminal equipment if the IP packet is intended for the DHCP server.

14. The method of claim 1 , further comprising: providing to the terminal equipment a Domain Name Server (DNS) IP address, a default Domain Name, an other Name Server IP address, an Interface Maximum Transmit Unit (MTU), or a combination thereof.

15. The method of claim 1 , further comprising: obtaining a gateway IP address from the wireless network, the gateway IP address being an IP address for an IP gateway used to route IP packets for the wireless network; and setting the router IP address to the gateway IP address if the gateway IP address belongs to the same subnet as the host IP address.

16. An apparatus for providing Internet Protocol (IP) connectivity for a terminal equipment coupled to a wireless device that is in communication with a wireless network, the apparatus comprising: A processor that determines a host IP address, a router IP address, and a subnet mask; and A transmitter that provides the host IP address, the router IP address, and the subnet mask to the terminal equipment, wherein the host IP address, router IP address, and subnet mask are used by the terminal equipment to exchange IP packets.

17. An apparatus for providing Internet Protocol (IP) connectivity for a terminal equipment coupled to a wireless device that is in communication with a wireless network, the apparatus comprising: means for determining a host IP address, a router IP address, and a subnet mask; and means for providing the host IP address, the router IP address, and the subnet mask to the terminal equipment, wherein the host IP address, router IP address, and subnet mask are used by the terminal equipment to exchange IP packets.

18. A computer program product, comprising: non-transitory computer-readable medium embodying codes for providing Internet Protocol (IP) connectivity for a terminal equipment coupled to a wireless device that is in communication with a wireless network, the codes comprising: codes for causing a computer to determine a host IP address, a router IP address, and a subnet mask; and codes for causing the computer to provide the host IP address, the router IP address, and the subnet mask to the terminal equipment, wherein the host IP address, router IP address, and subnet mask are used by the terminal equipment to exchange IP packets.
